thanks! we have that toy here, but the wheels are not that cheap. Oh well. I'll have to keep my eyes peeled on craigslist. thanks!
I've been looking for wheels like that for years, do you have a link for them?

1) a rocket stove is a stove design that creates a airflow by evacuating air and having input air sucked in. 2) fan would definitely improve it, just like any bellows. 3) LOL, I was up half the night designing a backpack version. The trick for a BP version is that it should fold flat. very do-able.
excellent advice. to clarify, the very best, absolutely safest ventilation is OUTDOORS. Also these duct sections I used are available without galvanizing in the first place, but following this advice, and then doing several burns, will remove any coatings/oils that are on the metals.
probably, but this design works quite well as is.
I recommend removing all ammo first though.
A friend of mine asked if I could make a rocket stove out of an ammo can. Turns out you can!
yes I read that article too. he was cooking many galvanized pipes, indoors, in an oven, generating, "flares off white zinc oxide smoke and leaves heavy soot like yellow and white oxide deposits...his was not a small amount of zinc smoke. It was thick enough in his well ventilated shop that..." This is a level of zinc oxide of about 10,000x what my 2 little pipes would do. I would still NOT use my stove indoors no matter what. same goes for propane, stoves, or just about any camping gear.
cooking test, fire started with just some leaves, twigs and pine needles. good flame, threw on a half a sawdust brick.
I was going for minimal. I don't generally pack a leaf blower when camping. Gas or electric, Not that I even have electricity when I camp.
I specifically used Non-galvanized duct work, but you are correct that galvanized steel, using zinc, produces toxic fumes (I'm told) However, as this is a wood buring camping stove, it is used OUTDOORS, so any fumes would dissipate. Also if you are worried, test fire the stove several times to burn off the zinc before using in close(er) quarters.
On galvanized steel:"I read a recent post which mentioned galvanized pipe and toxicity and realized this is a persistent myth in stove circles. I have a background as a chemist, my work includes machining and fabricating, and I think I know enough about galvanized to ease some fears and help dispel the myth.First, galvanized does not give off 'cyanide fumes'. It DOES give off zinc oxide fumes, which can cause metal fume fever. Metal fume fever is an immune-response condition that goes away in a day or two as your body absorbs the zinc. It's rotten, much like the flu, but it is rarely fatal, usually only when the exposure is extreme and the person has a pre-existing lung condition.

It's rotten, much like the flu, but it is rarely fatal, usually only when the exposure is extreme and the person has a pre-existing lung condition. It happens to welders all the time, almost considered to be a standard occupational hazard. Welders who work in a enclosed environment and don't wear protection develop resistance rapidly.Second, galvanized steel rarely gets hot enough to create said fumes except under conditions of welding, grinding or casting. During a stove test, I managed to oxidize 4' of my galvanized flue (it was under a fume hood, just in case). White oxides formed on the pipe but none was released into the air as fume. The fume is extremely visible when welding on galvanized material, as thick white smoke.Zinc boils at 907C, ZnO at 2360C, and rapid oxidation occurs at much lower temperatures near the melting point of zinc (420C). Once the zinc has been converted to oxide, it is safe. Your stove will never reach 2360C without forced air or oxy mix. I personally use a fully oxidized white zinc-coated elbow as part of a stove I operate indoors, and it is completely inert. I have never experienced metal fume fever myself as I always am sure to have good ventilation and a respirator if I weld galvanized material.I think galvanized is actually a better material for heat risers if you wish to use thin steel. The layer of zinc oxide will help protect the steel from oxygen and heat damage, I always use galvanized for heat risers in my small stoves and it seems to hold up very well. I always fire them gently at first to oxidize the zinc rather than melt it into a pool at the bottom of the riser. Any oxide fumes will find their way out the flue and not into anyone's lungs.Finally, galvanized steel is commonly used, within code, as an exhaust duct for gas appliances (go look at your hot water tank or furnace) and even to BUILD WOOD STOVES! Ex. www.rileystove.com/products/stoves/riley/flap-jack.html is constructed with 18ga galvanized steel! No Riley customers have died yet!"
I think I speak for a lot of folks in that its the epoxy that is the devil. I have no idea how to use it. Could you add some steps showing how the epoxy works? I mean from what to buy from the hardware store (what YOU actually bought,) what you used to mix it, prepare it, did you check the weather/temp?, drop cloths use, etc.) TIA, Jon
thanks for the description. I will want to see it step by step before I play the chemist.
thanks, but it was really nothing more than some drill holes and rough cuts with a 4 1/2" grinder
the real thing that inspired this build was also the firepit at the last camp site we were at was 100 feet away and on the wrong side of our camper. we wanted a fire closer to the center of where we camp. This little stove fits the bill.

until you gave the rules, I was just gonna spin the entire game board 180 degrees.
the best part of this instructable is the step by step creation of the mini-figs. I've never been able to do that right. thanks for the tutorial.
My wifes car actually has 5 cup holders, and its still not enough. Plus all of them are short (made for 12oz coffee's,) and the tall water bottles are always falling over. This one is custom to our needs: 6 made for the tall water bottles (and 24oz starbucks coffee,) and the two on the end for 1 liter seltzer bottles. so now with 13 cup holders for the two of us we should be ok.
